oh yeah, i think that 50 Games thing was made by Macro Winners, same as the 88 games joystick - most of the hacks from the 50 are on the 88 (but not Inclement Trip, so I still have no idea about that one). the Plug & Play seems to be by MW too, "Game Star" is one of their old aliases.. and the 30 in 1 looks identical to that, so that might be another one of theirs.
I'm also starting to think the 101 in 1 is MW's, I opened the Arcade Action 2 console the other day and it had a BS-something code on the PCB, which is the same code they use on all their other stuff. so theyre pretty damn prolific in the world of.. famiclones with terrible hacks on them, i guess.
